Installation
WARNING! Never run the engine in an enclosed space. Ensure adequate
ventilation at all times.
The pump must be situated on a firm, flat, level surface. Make sure that
the pump is placed away from the edge of any pit or pool and cannot
fall in. The suction and discharge fittings supplied with the pump are suitable
for 1" I.D. hose (not supplied). For best performance, keep the suction
pipe as short as possible, and make sure that all connections are airtight.
The pump will not work with air in the suction pipe.
For applications where the suction level is below the pump, we
recommend the use of a foot valve (non-return valve) to retain water in
the suction pipe. To prevent clogging of the pipes or pump, we suggest
that you fit a suction strainer to the end of the suction pipe.
Protect the pipework and the pump from freezing as the formation of ice
in the pump can cause damage. If the pump is installed in a location
likely to freeze, drain the pump (by removing the pump drain plug), and
the pipework after use.

Operating Instructions
The pump is designed to pump water. Do not use it to pump flammable
liquids or chemicals.
Before starting the pump engine, prime the pump by removing the vent
plug and filling the pump casing with water. Do not run the pump dry as
damage can result. Fitting a foot valve (non-return valve) to the end of
the suction pipe, and filling the suction pipe with water will speed priming.
Fill the fuel tank with 2-stroke fuel, mixed at the ratio of 20:1 petrol to 2stroke oil (50ml of oil per litre of petrol).
WARNING !
Never fill the fuel tank whilst the engine is running. Always stop the
engine and allow to cool before filling with fuel.
Starting
1. Open the fuel cock.
2. Set the choke lever to position ‘C’.
3. Set the throttle lever to approximately 1/2 throttle.
4. Pull the starter recoil rope slowly two or three times to allow fuel to
reach the carburettor.
5. Hold the pump down and pull the starter recoil rope firmly until the
engine starts. Do not snatch at the starter rope, and allow the rope to
retract slowly after each pull.
6. Once the engine starts, return the choke lever to position ‘A’, and use
the throttle to gradually increase the engine revs to the desired speed.
Note: Do not run the pump at more than approximately 1/2 speed, or run
it for more than 3 hours continuously, for the first 20 to 30 hours of use. This
allows the pump to run-in.
Stopping
1. Gradually reduce the engine speed to minimum.
2. Stop the engine by pressing the Stop button, situated just above the
recoil unit at the back of the engine.
3. Close the fuel cock.
4. If the pump is not to be used for some time, or is in a location likely to
freeze, remove the drain plug and drain the pump completely.
If the pump has been used with dirty or salt water, rinse it through with
clean water.

Maintenance
Clean the engine and pump assembly regularly, checking for any loose
bolts etc. Lubricate linkages with a general purpose oil or grease as
appropriate. The engine is lubricated internally by the 2-stroke fuel.
Clean the air filter at least every 30 hours of operation; more frequently if
the pump is used in a particularly dusty environment. Remove the air filter
cover and the air filter element, and wash the filter in petrol or paraffin.
Check the spark plug gap, and clean the electrodes, every 50 hours of
operation. The spark plug gap must be 0.6 -0.7mm.
Occasionally remove the exhaust silencer and shake out any rust flakes
which may be loose inside it, and check that the fuel filter is clean.
Storage
Clean the pump and engine, and drain the pump completely. Drain any fuel
from the carburettor and fuel tank, and store the pump in a clean and dry area.
Additionally, if the pump is not to be used for some time, remove the spark
plug and pour 2 or 3 teaspoons full of oil into the cylinder through the spark
plug hole. Pull the starter recoil rope slowly 2 or 3 times to allow the oil to coat
the internal parts of the engine, and replace the spark plug.
Troubleshooting
CAUTION: Do not run the pump dry as damage can result.
If your CD1fails to pump check that:
1. The pump is primed - prime the pump by removing the vent plug and
filling the pump casing with water.
2. The suction pipe is in water.
3. The suction filter (if fitted) is not blocked.
4. The suction hoses are not blocked or collapsed.
5. All suction pipe connections are airtight.
6. The discharge pipe is not blocked.
If the engine fails to start, or runs erratically, check that:
1. There is fuel in the tank.
2. The fuel is mixed at the correct ratio (20:1 petrol to 2-stroke oil).
3. The fuel cock is fully opened.
4. The spark plug is clean and the gap is correctly set.
